"New data shows that Rhea does not have rings as originally theorized, but instead has an exosphere of oxygen and carbon dioxide, apparently produced when the planet's magnetic field interacts with Rhea's icy surface. This painting of Rhea shows a large tectonic fault bounded by cliffs. Moons Mimas and Enceladus are seen in front of Saturn's edge-on rings with cloudy Titan far off to the right. It is summer in Saturn's southern hemisphere, and the gas giant's northern hemisphere, seen below the ring plane, shows its characteristic blue winter color."
